FIREARM.

SPECIFICATION forming part of Letters Patent No. 669,520, dated March 12, 1901. Application filed February 19, 1900. Serial No. ,672. (No model.)

To ctZZ whom, it may concern..-

Be it known that 1, ANDREW FYRBERG, a zitizen of the United States, residing at No. 3 Tufts street, in the city and county .of Worcester,in the State of Massachusetts,have invented a new and useful Ejector for Firearms, of which the following is a specification.

My invention relates to improvements in ejectors for removing shells from firearms, in which a positive means is employed to start the ejector proper and bring it under the restraining influence of a dog, which is then caused to release the same to the action of a spring that completes the travel of the said ejector, the initial movement of the latter and the releasing motion of the dog being brought about by throwing down the frame; and the objects of my improvement are, first, to provide an ejector capable of dislodging a shell from the barrel of a gun, however tightly it may fit in the first place or be held therein because of expansion after firing; second, to afford means for completely removing the shell after it has been started, and, third, to furnish a strong, durable, and inexpensive device of the class designated above that is automatic but certain in action and simple in construction. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- 7 Figure 1 is a side view of my invention as applied to a shotgun, showing the parts normally or initially disposed, a longitudinal vertical section of the breech of a barrel and a side view of a portion of a frame in partial section being shown in this as in the next figure; Fig. 2, a similar view showing the intermediate position of the ejector proper and relative displacement of the other parts in full lines and the extreme displacement in broken lines, and Fig. 3 a side view of the screw-key.

Similar figuresrefer to similar parts throughout the several views.

My invention, which is applicable to rifles as well as shotguns, will now be described.

The breech of the barrel 1 has the ordinary lug 2 depending therefrom, to which the frame 3 is pivoted by the screw-key 4. In the lefthand end of the lug 2 is the slot 5, and the passage 6 extends longitudinally through said lug from its right-hand end to said slot. The

ejector proper consists of the head 7, the body 8, and the tail 9, the latter being'smaller in diameter than said body. The body 8 and tail 9 operate in the passage 6, and the head 7, which is similar to any ordinary ejectorhead, is adapted to fit snugly into the recess 10 in the barrel 1, the upper surfaces 11 and 12 of said head being continuous with the interior surfaces of the breech of said barrel when the gun is closed. The flanged head of a shell when in position bears against the barrel-shoulder l3 and the ejector-head shoulder 14. The ejector proper is constantly tensioned to the right by the spring 15, which encircles the tail 9 between the left end of the body 8 and the shoulder 16 at the left-hand end of the passage 5. The said ejector is prevented from turning and has its travel limited by the pin 17, inserted in the lug 2 and extending through the passage 5 and the slot 18 in the body 8. The left end of the tail 9 is equipped with the downwardly-extending hook 19. The retaining-dog 20 is pivoted in the slot 6 by the pin 2i, inserted in the lug 2. The dog 20 is provided with the beak 23, normally extending upward into the path of the hook 19, and the depending finger 2a, which is capable of being-engaged by the nose on the left or front end of the frame 3. The fiat spring 26, which is attached to the under side of the barrel 1 by the screw 27, normally retains the beak 23 of the dog 20 in the path of the hook 19. The pivot or screw-key 4 is notched to provide the shoulder 29, and the tail 9 has the shoulder 30, adapted to be engaged by said shoulder 29 when the ejector proper is at the extreme left-hand end of its travel. The screw-keyi is loose in the lug 2 and turns with the frame 3.

When the gun is broken, the operation of my device is as follows: As the frame 3 is depressed the screw-key i and the shoulder.

29 forces the ejector proper to the right until the hook l9 encounters the beak 23 of the retaining-dog 20, when said shoulder clears the shoulder 30. A shell stuck in the barrel 1 is thrust out far enough to be easily freed therefrom by the next action of the ejector. All barrels are tapered slightly at the breech, so that it is only necessary to remove the head of a shell from the barrel in order to loosen the shell. The first movement imparted to the head 7, as above described, is sufficient for the purpose of loosening a shell. If there is no shell in the barrel or if the one therein does not bind, the spring forces the hook 19 into contact with the beak 23 Without the assistance of the positive action of the screwkey 4. The several parts now occupy the positions indicated by the full lines in Fig. 2. The continued downward movement of the frame 3 now-rocks the dog against its spring 26, through the medium of the frame-nose 25 and the dog-finger 24, until suddenly the hook 23 releases the beak l9, and the spring 15 drives the ejector proper to the right with sufficient force to completely remove a shell from the barrel 1, the movement of the said ejector being checked by the pin 17. It will be seen that two sequential motions are imparted to the ejector proper by the mechanism previously described. The parts now stand as shown by the broken lines in Fig. 2. When the frame 3 is elevated, the block 28 rides onto the head 7 and forces the ejector proper to the left against the resiliency of the spring 15 into its former or first position, while the spring 26 returns the dog 20 to its former position.

The end of the tail 9 is beveled or rounded off, so that it will easily ride down the dog 20 when returning to its initial position.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In an ejector for firearms, in combination with a frame and a shouldered pivot to attach the same to the lug of agun-barrel; a spring-actuated shouldered ejector proper provided with a hook, operating in said lug, the shoulder on said frame-pivot being adapted to engage the shoulder on said ejector proper to move the latter initially; and a spring-actuated dog pivoted in said lug, said dog having a beak normally extending into the path of said ejector-hook, and a finger within reach of the nose of said frame whereby said dog is rocked by said frame when depressed, to disengage said beak and hook after said frame-pivot has actuated said ejector proper until the beak and hook engage, substantially as set forth.

2. In an ejector for firearms, in combination with a frame pivoted by a notched screwkey to the lug of agun-barrel; aspring-actuated ejector proper provided with a hook and the shoulder 30 to engage the'screw-key shoulder 29, operating in said lug; and the springactuated dog 20 pivoted in said lug, said dog having the beak 23 normally extending intr the path of said ejector-hook, and a fingei within reach of the nose of said frame, whereby said dog is rocked by said frame when de pressed and the said ejector released to the action of its spring, after the hook on the same has been caused to engage said beak by the movement of said frame and screw-key, substantially as described.

3. In an ejector for firearms, in combination with a frame pivoted by anotched screwkey to the lug of a gun-barrel; a spring-actuated slotted ejector proper provided with a hook and the shoulder 30 to engage the screwkey shoulder 29, operating in said lug; the spring-actuated dog 20 pivoted in said lug, said dog having the beak 23 normally extending into the path of said ejector-hook, and a finger within reach of the nose of said frame, whereby said dog is rocked by said frame when depressed and thesaid ejector released to the action of its spring, after the hook on the same has been caused to engage said beak by the movement of said frame and screw-key; and a horizontal fixed pin passing through said lug and the slot in the said ejector to limit the travel of the latter, substantially as described.

4. In an ejector for firearms, in combination witha frame pivoted by a notched screwkey to the lug of agun-barrel; aspring-actuated ejector proper provided with a hook and the shoulder 30 to engage the screw-key shoulder 29, operating in said lug; the springaetuated dog 20 pivoted in said lug, said dog having the beak 23 normally extending into the path of said ejector-hook, and a finger within reach of the nose of said frame, where'- by said dog is rocked by said frame when depressed and the said ejector released to the action of its spring, after the hook on the same has been caused to engage said beak by the movement of said frame and screwkey; and means to return or initially dispose the several parts when said frame is elevated,

. substantially as described.

In testimony whereof I have signed my name to this specification in the presence-of two subscribing Witnesses.
